Hubble Protocol

Make your crypto work for you with Hubble Protocol.
Hubble is a decentralized finance (DeFi) protocol built on Solana. Hubble's core product is USDH, a decentralized stablecoin that can be borrowed against your crypto assets.

Users can deposit multiple crypto assets like SOL, BTC, ETH, and others, to borrow USDH. In turn, USDH can be used to serve various purposes across Solana DeFi.

Hubble will offer multiple USDH borrowing vaults, with various asset combinations and vault-specific parameters such as Stability Fees and Deposit Caps. USDH borrows are guaranteed by a combination of Hubble's USDH Vault (Stability Vault), and bots that facilitate market-based liquidations.

The USDH that users deposit into the USDH Vault is used to pay off bad loans, while depositors earn a net positive ~10% difference in liquidated assets. In addition, users who deposit USDH in the USDH Vault earn HBB, Hubble's native token.

In the coming phases of development, the protocol will launch various products and services to bring further utility to the platform, and USDH itself.

The HBB Token
Hubble delivers value to its community via HBB staking, allowing users to earn rewards generated by the protocol. In the future, HBB will be used as Hubble's governance token, which will empower users to direct protocol decision-making.

Building on top of the borrowing protocol, Hubble will offer a unique yield-generating infrastructure, as well as staking mechanisms geared towards adding further value to HBB stakers, while bolstering the value of HBB itself.

Borrowing made easy, cheap, and attractive
SOL, BTC, ETH, etc. holders, motivated to keep the upside to their portfolio, can deposit their assets and borrow USDH to use it across various protocols on Solana. While a user's loan is active, their assets retain full exposure to the market.

Upon paying back their debt, users will regain access to their collateral. If the value of their collateral increased while it was deposited, they receive that entire value back upon repaying their debt.

Loans have no fixed maturity, so debt owners can pay back their debt whenever they wish.

Earning yield on collateral
In addition to keeping the upside on collateral, users can earn yield on their deposits. At present, this is facilitated by Hubble's onboarding of yield-bearing collateral. Hubble currently accepts mSOL, stSOL and daoSOL as collateral, with Solend cTokens, stETH, scnSOL, and numerous other yield-bearing assets being onboarded imminently.

In the future, users will be able to opt-in to have their collateral allocated to partner protocols to earn yield. Users will have the freedom to choose from multiple yield-earning strategies.

Governance for the benefit of the community
Decentralized governance, in order to be meaningful, needs to allow the most active participants in the community to have an effective voice. To incentivize participation we are combining features of existing models that we find work best, especially:
• General directive proposals where development work from the core team is dictated by the community, once a quarter.
• Group proposals where the community can unite to make a proposal even if individual voters wouldn't have enough voting tokens.
